Its debut was a two parter that also marked May's first contest (and while she ultimately won due to points, the fight itself against Medicham ended in a draw). Both Hariyama and Medicham later had a memorable fight against Ash in the Battle Frontier.
Meditite's the one that got it bad because Brawly's Hariyama stole its spotlight in its own episode. And prior to that it debuted as a Makhuita but evolved mid-battle forcing Ash to have a rematch.
Looking back it's like the people behind the anime were very enthusiastic about showing how awesome Hariyama is.
