There is no explanation about how Tasuku used to beat Fuyuki's MetalGreymon with a Megadramon in Digimon World, but considering Megadramon can use Ice Statue whereas MetalGreymon cannot...
Back in the past, Tasuku likes to roleplay as Kouji from Digimon Frontier, while his big brother Fuyuki will roleplay as Kouichi. This is a nudge on their names, with Kouji being "Second Light" and Kouichi being "First Light," denoting that the latter is the firstborn of the twins.
Homare's story arc in A3 is about his Lack of Empathy and how he inadvertently hurts everyone with his words, even if he never means to. And Homare lamenting it is one of the biggest tearjerkers in the game. Then in Lava Cave, Homare ran wild as Vritramon. Guy came and tried to talk him out of it, but failed; Homare actively tried to kill Guy because he couldn't control himself. The scary part? Homare felt as his body moved by itself to attack his comrade. All while he helplessly watched, unable to do anything to stop the rampage. The cherry on top? For this fight, the author uses Guy's, not Homare's, point of view. Nothing Is Scarier indeed.
This is also why Homare can never regain control. One needs a calm mind to control the Beast Form.
The Past Experience Nightmare is quite disturbing itself. Homare, who had never entered combat in his life, was seriously injured in the incident, but the Past Experience Nightmare was not about him dying; rather, it was about him killing Guy. With Word of God saying that there was a Deleted Scene of Homare begging Guy to kill him right there in Lava Cave, this may cross over to a haunting Fridge Brilliance: the entire ordeal breaks Homare and it shows.
