Aside from his melanism, Raiden is a thin exemplar of a Pikachu. His eyes carrying a faint golden hue, he is almost always seen with his purple scarf.

Raiden is exactly what you would expect from an only child that was raised by a strict, law-enforcing father, and a loving, careful mother. His heart beats for justice, may it either be in the form of benignity or punishment. He finds joy and fulfillment in helping those in need, but also delights himself in seeing those who deserve it in pain, both physical and mental. He does not turn a blind eye on things, but has learned forgiveness in the presence of repentance. Though thinking of himself as anything but perfect, he still has a tendency to judge people at first sight, which is usually not a problem since most people in Invictus are decent, peaceful people. But it is hard for him to let go of his first impressions and try to see deeper in those he had already deemed nefarious. He definetly is a moralizer, always appealing to the good in the hearts of others. In a certain sense, he is almost patronizing.

Despite his tendency to procrastinate and minor clumsiness, he still manages to fulfill his tasks in time due to his unusual celerity. Not perfectly, but decently enough. Due to his melanism, he has always been treated 'differently'. Adults of course understood that it was but natural, and personally speaking, Raiden is a big fan of his dark colors, but children think differently. Those that were not jealous were always a bit anxious and avoided him if possible. He was not necessarily a lone wolf, but he only had a few, close friends during his childhood. He always enjoyed playing with others, especially if it envolved fast games like playing tag.

Mostly imposed by his father, he has adapted a daily routine of physical activity to steel his body, giving him a physique that is a bit more pronounced than that of the average Pikachu, or pokemon kids in general. He is not muscular or anything, but you can see that he has a slightly chiseled figure. He is nonetheless an adorable Pikachu for those that just wish to cuddle up to him. Raiden, as his name almost implies, loves thunders, and has hence focused all of his potential on mastering the art of electrokinesis, though in contrast, he is a very calm and composed being compared to the uncontrolled, violent force of electricity. His father had taught him a lot, but he discovers new methods himself as well, becoming a philosopher of sorts.

Raiden was brought into this world as an only child by his father Tyrell, a Raichu, and his mother Beatrice, a Cinccino. Capital born and capital raised, the Pichu enjoyed his childhood in modern civilization, ignorant to the misery of history before him. Like the well-behaved member of society he was, he attended school and exercised his duties without aversion. His melanism rarely got in his way, and it taught him the value of cordial friendship, though it made him conclude that prejudices were still a serious problem to this very day. This is why he is much more open to those stigmatized by society and rejects conservatism in any form unless it actually benefits all of pokémonkind.

Once he successfully graduated from school and matured to a Pikachu, Raiden decided to follow in his father's footsteps and enlisted in the military. To him, it was easiest and most legal way to do good and benefit the people of this world. All he wanted to be was being a guardian to the innocent and an adversary to fiends, and it was exactly with this promise that he was convinced to join the military. 

As a combat-oriented recruit, he is open to any form of duties, be they exploration or defense. Simply wanting to contribute to common good as much as possible, he is looking forward to do a good deed every day.
