* Completing the original ''Contra'' without the use of the KonamiCode. Now that has to be a reward to an experienced gamer.
** For bonus points, [[SelfImposedChallenge try fighting]] [[FinalBoss Red Falcon]] [[NintendoHard with only three lives]].
* ''Contra III'''s Stage 4 consists of a BattleshipRaid against Red Falcon's gigantic airship. How is this stage awesome? When you attack the airship's core, your helicopter launches [[MacrossMissileMassacre a series of missiles]] with you climbing on top of each missile as you attack the core.
** The final stage is a BossRush of six or ''seven'' bosses (depending on the difficulty level), with half of them being [[CallBack the final bosses from the previous games]]. [[NintendoHard Hard as Hell]], yes, but '''''awesome'''''.
* [[OneHundredPercentCompletion Getting an S rank]] in ''Shattered Soldier'' and ''Neo'' awards you with these two [[CrowningMomentOfFunny funny]] videos: [[http://www.youtube.com/watch?v=MrJ7zWGI9MI this]] and [[http://www.youtube.com/watch?v=6RCmbIwizjY&feature=related this]].
** Let's not forget that the latter video has Jaguar taking down hordes of enemies then destroying a giant robot that ''[[EarthShatteringKaboom literally causes the entire Earth to explode]]''. Complete with a ''Manga/FistOfTheNorthStar''-like finisher.
* The final battle with the Relic of Morai in ''Shattered Soldier'' and the final battle with Master Contra in ''Neo Contra''.
* In ''Hard Corps'', we get GTR (or Super Power Robot Yokozuna), who happens to be a large blue humanoid robot that has some skilled attacks. However, there are two things that just add up the awesome factor: his intro (he runs alongside the train you're walking on and then goes in front of it, ''stopping it with his own hands'') and his creative death (he falls off of the train and gets smashed to pieces by said train). The Contra creators must've thought that this was an awesome boss, because a MKII version of GTR appears in ''Shattered Soldier''. That one also stops the train with its bare hands after catching up to the train.
** It also helps that it has one of the [[https://www.youtube.com/watch?v=RLO5PDrgO1Q best boss musics in the series]]. So awesome, it [[https://www.youtube.com/watch?v=jcApUEVa7G8 got remixed]] in ''Rebirth'' for the mechanical bosses.
