Just a normal fight, unlimited heal, but this time, you don't heal to full HP, but instead, you're able to heal more HP than you originally had from the start. And, Sonic, the bot now does multiple moves than just 1 plain move in the previous RPS games. Beware, some of Sonic's moves does a lot of damage. So better heal when below 70 HP.
you can do combos but there is a 50/50 you have 400 more health and sonic has 1000 health
