What cliches/tropes in anime do you love?

Since we already have a thread on cliches we hate, how about cliches in anime that you love? The tropes I can never get tired of when it comes to anime is the first OP playing during the last battle/climax, the old "MC's rival turns good and turns out to be a total bro"-thing, or the final battle just boiling down to a fistfight. :V
