I was doing some rereading and I think that Bart Allen acted more like a Thawne than an Allen at times when he was The Flash in The Flash: Fastest Man Alive. And particularly so when he was fighting Thad because he was tapping more into his anger and rage which are very explicitly associated with Thawnes in the comics.

It’s seen with Malcolm Thawne (Barry Allen’s twin brother), who began the Allen-Thawne feud and also created the Cobalt Blue gem due to the immense amount of rage and wrath he held:

(The Flash (1987) #145)

It’s seen with Eobard, Thad, President Thawne, Meloni even states she had a desire to smother her father in his sleep (which is great and I support her), and generations of Thawnes who are able to tap into the power of the Cobalt Blue gem which is based in hatred.

This hatred with regard to Malcolm’s descendants is associated with the Thawne ideology and is a learned hatred, but I think interesting that his character also has instances of following this pattern and characteristic associated with Thawnes despite being raised as an Allen and as a hero. I also think it’s interesting because Bart’s character and writing surrounding on him has never personally touched on or associated him with Thawnes except for stating that his mother is a Thawne and that his grandfather, President Thawne, wanted to convert him to the Thawne side. Bart has never weighed in or commented on this half of his lineage.

But even despite that Bart doesn’t seem like he’s an exception to this pattern/characteristic associated with Thawnes because he also displays this intense rage too at times such as seen when he is The Flash. He breaks his knuckles on Thad’s face and when he sees the Black Flash, a certain sign of a speedster’s death, he actively tries to kill Thad. It is a kill or be killed situation, but typically heroes and Flashes specifically tend to stay away from killing. And similarly in Teen Titans Bart wants to get revenge on Thad after his death (and for context Thad has already died himself due to the fact he killed Bart), even despite this being a simulated version of Thad feels very Thawne like as well because he’s not just punishing this version of him, but is once again actively desires to kill him.

So while it does seem unlike Bart to give into rage or anger this intense it’s interesting to think that Bart also holds a tendency toward anger or rage at times that connects him back to the Thawnes and this prominent theme/characteristic associated with them with regard to his character, and is also ironically used against them.
