Yeah, She Hulk will be good enough for ikarus, but it'll still be a tough fight. Mystics are the preferred attackers for ikarus.
I used double cmm and guardian. 2 5 stars my 6 star was r2 cmm. Guardian clapped kraven 2 revs, scorp was r2 cmm solo, ikarus was...40 revs don't EVER use cmm for that fight it will make you want to quit...the rest was a breeze cheers!😁
