did you look at the dungeons and dragons games? they could be helpful!

Two things I've noticed.

1. Your animations are not fluid at all. I'd definitely consider adding more frames because as it is now, many limb movements seem to jerk a bit.
2. Your goblin helpers sprites clash hard. I see slightly edited Samurai Shodown sprites (from multiple games in that series) mixed with sprites from very different sources.

Looks great. For the style - a suggestion would be to not have the ability to jump around too much but be able to walk through fireballs to show true power (i've seen a ghost/phantom ryu do this). Maybe have the stage shake with each step which i've seen before with juggernaut. Like serious power with massive mallet attacks (like the movie) that knock the opponent across the screen which would look great in 1.1 long zoom stages.

This is a nice boss char, do you plan on making any more boss characters? And about the normal attacks not killing her the same thing happens with robotnik. Was that intended?

Olá Flavio!
Really very interesting this Robotnik, i'll give a try for sure.

watched the video. you put great effort in this! downloading.
is this a boss char?

I know right I tried once but failed...to tell the truth I like the look of alexia from code veronica but like the personality in darkside chronicles well least your the first to try to make alexia
