Simply put. Optimus Prime had Megatron Blaster had Soundwave Metroplex had Trypticon Did the other Autobot's have a rival that they most frequently battled with? Example, who did Jazz usually fight against?
There's Depth Charge and Rampage from BW too. And I guess Lockdown turned out to be Prowl's rival in TFA.
Fort Max vs Scorponok Dinobots vs Constructicons Sky Lynx vs Predacons Star Saber vs Deathsauras Countdown vs Skystalker All of the original 12 Pretenders have rivals
Fortress Maximus had Scorponok. That's the only example I can think of off the top of my head, but I'm sure there's many more. EDIT: Beaten to it by Thundershot
Silly me, I forgot about Fort Max and Scorponok as well as Dinobots and Constructicons. Actually, I thought it was Omega Supreme and the Constructicons?
Not directly (there's no "rivals" page, nor do I think there should be). And it's the TFWiki. Anyway, Quickstrike from Beast Wars basically had a rivalry with anyone who dared to say he's not the toughest of them all. Then there's all the combiner rivalry like Combaticons vs. Protectobots, Terrorcons vs. Technobots, Stunticons vs. Aerialbots, etc. I think the Predacons hated the Dinobots as well. Ooh! Shockwave and Lugnut had bit of a rivalry going in the last two episodes of Animated.
Rodimus and Galvatron, Big Convoy and Magmatron, and RID Optimus Prime and both Megatron and Scourge as well.
Here are the ones I can list from the top of my head: G1 Prime Vs Megatron Blaster Vs Soundwave Dinobots Vs Devastator Beast Era Depth Charge Vs Rampage Rattrap Vs Dinobot, later Depth Charge, and later Botanica Cheetor Vs Waspinator, later Thrust Silverbolt Vs Megatron and Thrust in BM Movies Prime Vs Megatron Bumblebee Vs Barricade Sideswipe Vs Demolishor Ironhide Vs Bludgeon Ratchet Vs Lockdown Animated Prime Vs Sentinel Prime Ratchet then Prowl Vs Lockdown Bulkhead Vs Blitzwing and/or Lugnut, later the Constructicons Lugunt Vs Shockwave Blitzwing Vs Blitzwing Vs Blitzwing - remember his three face deal?
Chopperface, I think we should clarify whether the topic is stating about competitive/on-the-same-side rivalries or antagonistic/archenemy rivalries. I was under the impression that this topic was about the latter.
Cyclonus and Magnus from the G1 cartoon Omega Supreme and Constructicons Megatron and Starscream Dinobots and Shockwave from the comics
Superion vs Menasour Defensor vs Bruticus Computron vs Abominus Ultra Magnus vs Cyclonus Sky Lynx vs Predaking Blaster vs Soundwave Sandstorm vs Octane (although this was more of a friendly rivalry)
I thought it was interesting that Shattered Glass likes to give their characters the color scheme of a rival or "opposite number" on the other side, i.e. Cyclonus in traditional Hot Rod colors. Though I think that has as much or more to do with toys that came out at the same time to "oppose" each other (i.e. Abominus and Computron get the color-swap) than with actual in-fiction rivalry.
How about Eject & Rewind vs. Rumble & Frenzy Steeljaw vs. Ravage even though I don't think I ever saw them fight eachother. Hmmm
