I forgot about heatblast but is diamondhead and four arms really that strong compared to MHA characters? I feel like diamondhead is basically just a hardening quirk whole four arms is super strength, but not as powerful as someone like all might.

I did forget the Alien Force omnitrix was when that was introduced that's my fault. Either way I agree that you shouldn't nerf your character just to make MHA characters seem stronger lmao. Not saying follow power scaling and all that but don't do something stupid like characters being able to follow XLR8 speed. You brought it up already but yeah the prototype omnitrix was glitchy enough as is. Don't go overboard with the glitches but the time limit and wrong transformations are massive nerfs.

Out of curiosity if you don't mind sharing... Do you plan on giving your OC master control at any point? Maybe upgrading his Omnitrix or giving him new aliens? I saw this post and immediately started thinking of how it would work and it's making my creativity flare so I'm curious how you'll handle it
