Why not counting Sacred Gear Cancellar...simple because i talked about pure Raw Power...SGC has nothing to do with power (only about power to cancel SGC^^)

Vali said once that to fight Tobio he would need to use Juggernaut Drive...and it is said the JD brings out the full Power of a Heavenly Dragon (ok we know this is not fully the case...but Issei with JD smashed Shalba Beelzebub easily...while Shalba had ophis snake and was on the Powerlevel of Original Maou Beelzebub..or so it is said.

So Tobio is not weak...stronger than Maou...and Rizevim is the weakest Superdevil
