If you just want to defeat him, use Twister or other spell removals to destroy his Toon World. Any face-up toon monsters will be destroyed, and Pegasus will no longer be able to special summon some toon monsters, or attack directly.
Note Pegasus may use Judgment of Anubis to negate the activation of your spell removal card. Additionally, he has another Toon World.

I was there for the pegasus event, but was new so I couldnt get dmg. Honestly, its kinda a necessity in toons and its a shame that theres no good way for people to get it. Maybe a pegasus event again but people who already have dmg get an sr jewel instead
Pegasus is now a permanent gate duelist along with the Paradox Brothers. I don't know what their unlock conditions are though.
So i spent the sr ticket i got from answering servey and 1 gx sr ticket on toon world for my toon deck and i wanna know if i made the right choice or fucked up cos been dueling with pegasus for almist a year now and still not its a toon world and cant get it as a duel reward at the gate either
