Maybe this arcticle would better off being named "List of references to other video games", to include the Digger Drill's reference to Drill Dozer and other such instances Manga-in-a-bottle 06:16, 10 June 2007 (UTC)
Not just other videogames, since I can think of some film and television references as well. --Zeta 09:32, 10 June 2007 (UTC)
I think it would be a good idea to expand the subject of this article to other Game Freak games, since the original Pokémon games had a reference to Mario & Wario (the Copycat had it in her SNES). --Evice 21:58, 30 August 2009 (UTC)
I think you guys missed a huge bit of trivia. Bisharp is another Pokemon directly based on Pulseman. It's pretty obvious when you compare the two. I mentioned it in the discussion page of Bisharp as well. (Flintlock (talk) 06:08, 17 June 2012 (UTC))
I noticed that a bit of trivia says that Regigigas resembles a boss at the end of one of the stages, but I went on youtube and watched a playthrough and he really resembles Registeel more than Regigigas. It's a metal floating ball wiht dots for eyes...
