Suggested by iKnowledge Elder Toguro is extremely dangerous because his regeneration pretty much has no limits. The guy’s been scattered into dozens of pieces and completely squashed, but always gets back up. That being said, he has never dealt with someone who possessed as much raw power as Yomi. Yomi could obliterate him with a powerful energy blast and the fight would be over in an instant. No regeneration can protect you from something like that. Yomi wins.
