Dave does not have fond memories of Randy Orton. Randy doesn't have very many of those of him either thanks to the chip on his should caused by Evolution's betrayal. Even then, however, neither Dave nor Randy consider each other to be one of their primary arch-enemies, seeing as while they do hate each other, they have much more beef with others. Dave had a lot of issues with The Undertaker over the years, and as much as Randy hates Dave for his part in Evolution's betrayal, it's is to a far lesser extent than the pure loathing he has for Triple H.
Bald of Evil: As Leviathan and during his last heel run and his 2014 return. He grew a full beard during his Evolution reunion.
Beard of Evil: He also started sporting a pretty dark five-'o-clock shadow during that 2010 heel run as well.
Big Eater: As shown when he was a guest judge in an episode of Iron Chef America. He was apprehensive at first when the secret ingredient turned out to be snails, but he pretty much devoured the food with great gusto once judging came. Some of the dishes were even served to him on bigger plates than those of the other judges.
But Not Too Foreign: He's a Greek Philippino, not that WWE has ever mentioned the fact. For awhile, viewers South of The Border thought he was Mexican American, leading him to receive a popularity boost Latin markets and be put in an angle with Eddie Guerrero.
Chewing the Scenery: After turning heel, Batista started putting his propensity for ham to good use.
The Giant: Especially in OVW, even when he was fighting Brock Lesnar, the main thing to his matches was being big and throwing/squeezing the other guy while not being knocked down.
Glass Cannon: He gets injured a lot, both legitimately and in story lines. That said, big Dave is known as big Dave for a reason.
Heel-Face Turn: After Randy Orton was kicked out of Evolution by having the audacity to win the World Heavyweight Championship, which Triple H still believed was rightfully his despite his inability to win the title back after losing it at WrestleMania 20, Batista slowly began showing signs of dissent as he began to realise that he would never be able to become World champion if he remained part of the group. He ultimately left Evolution & turned Face in the process as he elected to use his WrestleMania title shot by virtue of winning the Royal Rumble to face Triple H.
He's Back: He returns to WWE in the January 20 edition of Monday Night Raw to challenge Alberto Del Rio... as a Face.
The first thing he does upon his return? He wins the Royal Rumble.
Humiliation Conga: The months after WrestleMania XXVI to his 4 year retirement could count as this right up to his last night. Also might qualify as a Downer Ending.
Irony: Batista quit because Triple H told him that nobody in Evolution would be getting anything they wanted until the Shield no longer existed. After he quit, Triple H invoked his Plan B, which was Seth Rollins defecting to his side, thus destroying the Shield. In other words, Batista quit because he was frustrated that he wouldn't get what he wanted until a seemingly-impossible goal was reached... but by leaving, he made reaching that goal possible.
It's All About Me: His 2010 heel run was centered primarily on demanding recognition from all around him.
Large Ham: His final heel run, to the point that he would only cut his in-ring promos after demanding that a spotlight be shone on him and only him.
Last Name Basis: John Cena calls him Dave Batista, specifically to emphasize his lack of fear of him, but otherwise this is the case. Evolution stablemates are prone to calling him Dave too for more respectful reasons.
After repeatedly failing to beat John Cena for the world title, and getting injured in a match, he quit WWE. But that was only on Kayfabe, because he had later stated that he didn't like the direction in which the company was going.
He also admitted in his return interview that he actually suffered a legitimate back injury during his "I Quit" Match with John Cena, which only sped up his decision to leave.
After Triple H made it clear that no one in Evolution would get what they wanted until The Shield was no more, Batista said he understood, and then that he quit.
Sleeves Are for Wimps: His outfit as Deacon Batista consisted of a suit without sleeves (he mentioned in an interview that when he was told to get a suit, he felt it was important to really look the part. He bought a very expensive suit at a time when he really couldn't afford it... then looked on in horror as they immediately hacked off the sleeves.) His 2014 run involves asking where are the real men, and he seemed to be frequently decked out in tank tops, vests and other sleeveless attire.
10-Minute Retirement: On the record to saying he would like one more match/brief run with the WWE before taking an executive role in the company.
Played Straight so far. He returned in 2014, just in time for the Royal Rumble. And WON the Royal Rumble match, punching his ticket to the Wrestlemania 30 main event.
Too Dumb to Live: His 2009 Face-Heel Turn? Yeah, it basically happened because Batista apparently assumed that being in a Fatal Four Way for the World Heavyweight Championship with Rey Mysterio Jr as one of his opponents meant that Rey wouldn't actually try to win and would just help him. Especially when Rey later admitted that if Batista had just asked him to help him, he would have. Then again, it's Insane Troll Logic, which is standard operating procedure for most heels.
Wrestling Monster: Leviathan, which was part of the reason his later Deacon Bautista run was so underwhelming, since the gimmick change was not really needed to fit with D-von Dudley's preacher gimmick.
