I want an Install done properly dammit. Other ideas I'm very fond of are the following
1: Time manipulation, I see this working by having the character create a bubble where time slows down or stops completely for whoever gets inside, like the Swirlix Pokeball, only to gradually shrink until it disappears and you need to wait for the cooldown to wear off.
2: A heavy who can ignore projectiles, I came up with this when thinking of how Edelgard could work and her personal skill in 3H is that she gains a massive Res buff if she ends her turn by waiting, meaning magic is less effective on her despite being her weaker stat. The way I see this working is kind of like Deep Breathing but if you pull it off, you'll have armour that works on every projectile in the game for a limited time. The idea of a heavyweight who's slow but can't be zoned out sounds really ****ing good to me.
3: Android 21. For those who don't know, 21's gimmick in DBFZ is that if she uses her command grab on a character, she'd copy a new move from them, the move depending on what kind of character she hit, which iirc were Goku family, Vegeta family, Alien and Other. The best characters I can think of for this are Velvet Crowe and Soma Cruz and I see this working great. To help visualize it, if Velvet hit someone with electricity proficiency like Pikachu or Samus, she'd get Thunder Blitz, if Soma hits someone associated with fire like Mario, Captain Falcon, Charizard, etc then he'd gain the classic Hellfire attack
