Smash Legend
Self-explanatory
Waluigi: For Waluigi, it'd seem obvious to choose Waluigi Pinball, but I'd personally choose something that sounds more victorious - a Mario Tennis 64 medley would be my choice, with Break Point 2 as the focus of said meldey.
Jill (Drill Dozer): Third Gear, not using this song would be like not using Gangplank Galleon in a K. Rool trailer, it's a song so synonymous with the character.
Muddy Mole: A hard one, a Mole Mania medley seems the safest bet - but if it's a remix of a single song, Forest seems a good choice since it has recurring motifs in Mole Mania
Crash Bandicoot: This guy has A LOT of options - I'd do two trailers for different regions, using slightly different footage, given how this character is perceived differently in certain locations. the Eastern trailer would feature the Japanese Crash theme while the Western version would use N. Sanity Beach
PaRappa the Rapper: this guy's all about the music, but the problem is that all his songs are either about love and peace, or extremely situational, remixes wouldn't really work well for his trailer either since he has a very distinct music style, it'd be like using the Ultimate version of Splattack in an Inkling trailer - the best choice to me would be the instrumental of Toasty Buns. Alternatively they could reveal him alongside some other PlayStation All-Stars in a single trailer with Finale playing
Dr. Eggman: Ruby Illusions would be my instant choice - mostly because there's tons of really clever ways you could use the song's build-up. I feel E.G.G.M.A.N. would work too, as a more "cool to be bad" theme.
