I think I can try it, just for fun i guess:
Name: Callum ??? (Surnames are hard, but since few people knows, there's no prob)
Nickname: Cursed blader (he didn't give it to himself and he hates it)
Age: 14 (funfact, his birthday is on a ??/13/????)
Bey: Old: he didn't had a beyblade back then, he got one basically at the start of sparking.
Current: Swirl Caribdis Polish' Depth 1D (DS-hibrid balance type, right-spin, sparking system)(DS-hibrid = defense and stamina)
Physical Appearance: black (and a lil messy) hair, dark brown eyes, almost pale skin and a little bit skinny. He wears a black hoodie with a purple fire pin on it, on the middle of the hoodie there's "not my problem", black pants, non-matching socks and grey boots-like sneakers.
Noticeable feature: His face is blocked by a mask resembling the shy guy mask, but without the mouth hole, not painted and with a crack from left eye all the way down.
Personality traits: Callum is shy and don't talk with anyone else than family and close friends (he "talks" with close friends), plus he has some anxiety, but that doesn't stop him. He has a really good memory and uses that as an advantage. When near people, he tries to ignore them as much as he can. He also has sleep problems.
Likes: Being alone, playing with his sister, planning ahead and play safe, also I can include onions, he can eat one like a apple (not like he does that normally, but he can and isn't bothered by the onion part, it's a ability)
Dislikes: crowded places, losing, unexpected things, people over-excited that always wants to battle and, of course, cheaters.
Character alignment: True neutral, almost sure.
Backstory: so lets see... he and his sister went to their grandmother house because their parents are always travelling for work and etc. He suffers from social negligence from everybody, the mask works as a emotional stabilizer (like a social support puppy), one time someone made fun of his sister and he almost destroyed the opponent bey (he didn't meant to but at the same time he meant(plus the opponent and the "someone" are the same person)), everyone got scared of him and started calling him the cursed blader.
(I may not tell more because (maybe) I'll write it and post somewhere so that's what i got for now, not gonna spoil that much)
Special moves: he has one for each mode
1° special move- ocean guarding: pure defense mode, just like any def. Move, blocks attacks, but deals increased knockback.
2° special move- swirling dash: driver is in stamina and layer in defense, it stays on the free-spinning plate and move like a cone (since is only the plate making contact) and deals increased dmg.
3° special move- wave resistance: pure stamina mode, inclines and let the enemy bey hit the forge disk instead of the layer, if it touches the floor, it just dash through the arena like crazy almost doing dread vertical until it gets up, hard to do it tho.
4° special move- tide breaker: layer is in stamina and driver in defense, because of its circular shape on stamina mode, it blocks all the attacks on the layer and only layer.
5° special move- direction change (it's a "defect", wasn't supposed to happen): change layer and driver modes randomly depending of the circumstances.
Launching technic: nothing really crazy,he just swings his arm back and forth, do a launch flip, get in position on last sec and tada
Launcher: it's worth mentioning that his launcher has a gear system that makes his bey go faster when he launches with left hand, his left arm is (canonically) weak so this balances it out and launch with the same power (doesn't change spin direction).
Relations: obviously his twin-sister, Sarah: they both like and help each other, she is his polar opposite socially. Also she made him get into beyblade after showing him her own bey.(easy to guess the name)
Kiaru Yofutoremi: One of his only friends, Kiaru follows Callum since he saw what happened on the "cursed blader" thing, they both walk together and train together, it's a wierd realtionship, since both don't talk that much.
(Note: this is about the present time, im planning on add one more person here)
Quotes: . . . . . he got some:
"Never do that again..." When he almost broke a bey.
"Awesome, hope your ready for mine..." When his sister shown her bey
"We got this..." To Kiaru while waiting for their tag battle. (Prob written on WBO Blader brawl)
(Those are the most important ones)
(He's still in development and I'll maybe write about "his story" in general, also it's my first character (written and public shown)(note: english isn't my native language, expect some misunderstanding)(🎵 2: he's not evil))
Rank 0th means I'm better than 1st
