What dark and scary G1 episode do you guys think is now considered tame by today’s standards?

‘Return of Tambelon’ featured a very demonic Grogar that makes G4’s Grogar look harmless by comparison, resides in a dark and gritty city, and his army conquered most of Ponyland within days with no resistance.
