Ace Grit (エース・グリッド, Ēsu Guriddo?) is a 16-year-old Vestal. He is the Darkus brawler in the Bakugan Battle Brawlers Resistance. His Guardian Bakugan is Percival (later evolved into Knight Percival), and his Trap is Falcon Fly (later evolved into Flash Falcon Fly). Mira Fermin convinced him to join the Resistance one day after defeating him in a brawl, then giving him Percival to prove that Bakugan were sentient and not just mere toys to be played with.
Ace's only major appearance is in Bakugan Battle Brawlers: New Vestroia. Notably, he is also the only member of the Resistance that is not playable in the video game Bakugan: Rise of the Resistance, as he had been captured by the villain Hurranians; the game-exclusive character Eva-Q8 fills in the Darkus brawler position in his place.
Ace is a 16-year-old Vestal boy, with pale green-blue hair and cool grey eyes. He wears a purple long-sleeved shirt, with black and grey trimmings, grayish-white (sometimes shown vibrant blue instead) pants, and black boots. Mira found him and convinced him to join the Resistance after beating him in a battle and showing him that Bakugan could talk when she gave him Darkus Percival.
Ace is very cocky and hot-headed, which usually gets him into troublesome situations that make him regret the things he says. At first, Ace disliked the idea of having humans join the Resistance, but after tying in a battle with Dan Kuso, he accepts Dan and Marucho Marukura into their group. The similarities between him and Dan have caused tension between them.
He developed a heated rivalry with the Aquos Vexos Mylene Farrow with the two having battled twice and having one win each (Ace only beat Mylene due to Klaus's help). though their rivalry is never truly resolved—Mylene (and her partner, Shadow Prove) would eventually perish after causing Bakugan Interspace to collapse with a dimension bomb following her defeat at Mira and Keith's hands.
He has feelings for Mira, although she is rather oblivious to this fact, and has displayed his protectiveness of her many times through the series. He shown to be jealous of Dan, due to Mira's attraction to Dan, and Keith Fermin, since Mira spends a lot of time with her brother. Because of this, he has a better friendship with Shun, although at first, they did not see eye to eye, mostly because of his cockiness and stubbornness causing him to misinterpret Shun's actions. Ace is sometimes sarcastic, often questions others' ideas, and is also very prideful. He lives alone; this explains his independence and sometimes coldness. But to sum it up, Ace is a good-hearted young person with a proud, stable personality, is not fearful, and is always eager to help his friends.
When Dan and Marucho arrive at the base Baron Leltoy is shown to be a fan but Ace gets jealous, He challenges Dan, thinking that Dan and Marucho didn't belong in the Resistance. The brawl ends in a tie, and they earn each other's respect, though some tension still exists between them.
In Marucho's Mission, he taunts Dan calling Marucho a deserter much to Dan's anger and finds a stranger beat Mylene.
On their way to Alpha City, he and Mira Fermin argue: Mira wants to postpone the assault of the Alpha Dimension Controller to look for her brother, and Ace fears that she could get hurt. Later on they met Shun Kazami after he helped Dan defeat Spectra and Gus and agreed to join in hopes of finding Skyress. Shun then tells the group the story of how he arrived in New Vestroia and began fighting to free the Bakugan. Shun leads the team to Alpha city where they explore the city and find out about Altair during Mira's Brawl with Lync.
While deciding which two brawlers get to enter the Alpha City tournament, he and Shun Kazami are paired together. At first, Ace doesn't like Shun interfering with his battling style, although Shun is helping. The two's constant bickering nearly costs them the semi-final match, but they manage to set aside their differences and advance to the final against Lync Volan and Volt Luster. The two successfully stall for time and lead to defeat Lync's Altair together. Shun mentions that Ace is a lot like Dan, which is true. Afterwords the Bakugan thank the Resistance for freeing them.
When Runo arrives on New Vestroia, Dan, Mira, and Baron Leltoy accompany her back to Earth after Spectra Phantom, Gus Grav, and Lync follow her. He worries about Mira, and when he hears her voice in the night (which was Shadow Prove leading him into a Vexos trap), he tries to save her, which further shows his love for Mira. In the same episode, it was revealed that Ace often refused to join tournaments in the past. He was approached by Mira and lost to her in a battle, after which she welcomed him to the Resistance and gave him Percival. After being defeated by Mylene, he is seen as a hostage along with Marucho and Shun but is later freed by Spectra and Mira, though he is unaware that they released him.
When Dan told him that Mira betrayed the Resistance, he refused to believe it due to his feelings for her and gets a little violent by grabbing Dan's collar, but had to believe it was correct when he heard Baron's side of the story, which was the same as Dan's. The group later arrives at Gamma city where they learn it connects to the vest palace.
When the Resistance get inside Gamma City, he and Dan battle Gus and Mira. He is shown to have a lot of faith in Mira which was proven true when Mira betrays Gus and helps him and Dan win. Later he is shown watching Dan's battle with Spectra and goes to free Mira Shun and Marucho from the Vest palace alongside Baron. He returns to Vestal with Baron and Mira and their Bakugan after Prince Hydron is defeated and Tigrerra, Skyress, Gorem, Preyas, and Hydranoid are freed, in case the Vexos will want to take back New Vestroia for themselves in the future.
Along with Mira and Baron, they went on live television to tell all of Vestal what King Zenoheld had been up to and how Bakugan are intelligent creatures. This prompted the royal family and Vexos to flee Vestal to escape prosecution for their actions.
After their return to Vestal, he is called by the Six Ancient Warriors along with the rest of the Resistance. He receives the Darkus Attribute Energy from Exedra, causing Percival to evolve to Knight Percival. Following Percival's evolution, Ace helps Baron find an apartment for himself, as his family is large and crowded. While browsing around a future building site of new apartment buildings as he daydreams of living in a building with the Resistance but without Dan, Shun and Marucho (showing that despite being friends, Ace hasn't accepted them at all). He's attacked by Mylene and her new mechanical Bakugan Aquos Macubass. Ace struggles against her new Bakugan, and the Darkus energy is nearly taken. However, Klaus von Hertzon and Sirenoid arrive and help Ace defeat her. Ace initially doesn't like Klaus because he doesn't like being helped. Also, Klaus openly called him "Ace my boy," which made him very mad.
When Mira, Dan, and Marucho arrived to Vestal, Klaus kissed Mira causing Ace to say "Heeeey! Dude!" in a tone of jealousy. Later he is frozen as Dan Mira and Marucho battle Spectra.
After Shadow Prove attacked Alice on Earth, the Resistance heads back to Earth and takes refuge in Marucho's mansion.
When Marucho and Preyas sneak out to find Elfin, he is with Shun, Dan and Baron sleeping through a romantic movie that Runo, Mira and Julie are watching. A few days later he plays cards with Dan with the latter complaining how he only knows ability cards while Maron Leltoy pays the team a visit.
After Julie Makimoto watches him work out with Dan, she develops a crush on him, spurring Mira's jealousy. With Billy's surprise arrival, Mylene and Shadow Prove had discovered their hiding place. When Marucho shows them his virtual trainer, Ace is paired to fight with Billy Gilbert. Julie attempts to switch numbers with Billy and Mira, then Runo reveals her crush on Ace, making Billy jealous. Ace, not wanting the break up the "lovebirds" as he calls them, challenges them both and manages to defeat Cycloid and Gorem with Percival and an evolved Flash Falcon Fly.
When the Resistance chooses to attack the Vexos Motherpalace and the BT System, Ace and Marucho rush to find Dan and Mira. However, they encounter Shadow Prove and Lync Volan, who, using the Mother Palace to secure more power for their Bakugan, cheat to their victory, securing the Darkus Energy from Percival. Dan loses the Pyrus energy to Zenoheld after his brawl against him and Prince Hydron, paired with Mira and Spectra, and the BT System fully operational, Ace heads with the Resistance and Spectra to New Vestroia to evacuate all the Bakugan. Marucho heads with him to set the coordinates for his house to send the Bakugan. However, he immediately insists on joining them, showing that Ace is still obviously distrustful of Spectra. Even after Spectra helps Ace still is suspicious.
After the BT System is destroyed, Ace stays on Earth along with Baron and Mira. When the phantom data appears in Bakugan Interspace, Ace and the others entered the virtual world and watched Baron battle against a clone of Haos Aranaut.
Ace accompanies Dan to watch his final match with Spectra, and after his defeat, he officially joined the Resistance, Ace is still cautious about him. He resents the time Mira and Keith spend together. Julie pointed it out and told him not to be jealous because the Clays are only siblings. Even Percival said that he needed to relax about it. Also, he seemed to be a bit jealous when Mira paid more attention to Keith instead of him.
When the Alternative is complete, Ace, along with the rest of the Brawlers, battle it. Four of them went inside the Alternative and destroyed the core. After that, he bids farewell and heads back to Vestal with Keith Fermin, his sister Mira, Gus, and Baron in Final Fury. In the Japanese Ending of this episode, Baron accidentally hits a ball on him while playing with his siblings, and an angry Ace chases him.
Bakugan Battle League
In the Bakugan Battle League canon, Ace returned to help get Marucho out of Bakugan Interspace but lost to Shun in a battle to see who would go with Dan to Bakugan Interspace, so he waited outside of this place.
