Tenma looks largely like his dad, same charm, jet black hair usually kept in a small ponytail, bangs framing his face, light skin, dark eyes, quite a bit smaller than others his age due to his premature birth and growing up in the Akatsuki where it wasn't easy to get decent nutrients for a baby. He is agile, light, hard to hit, and fast, using his smaller height to his advantage to slip away and evade. But Tenma is naturally slim and gets tired faster from physical exercise than others due to the same reasons but he does fill out slightly overtime. While growing up in the Akatsuki he wore fairly traditional clothes, simple high collar dark blue shirts, black pants, usually a raincoat and boots, but his style changed drastically after being unsealed and joining Kara. Tenma cut his hair shorter while keeping the right side of his bangs long and it covers most of the right side of his face, his hair has a subtle dyed dark blue undertone and is quite unruly. Tenma does also have subtle eyeliner around his eyes and his nails are painted teal.
Outfit wise, underneath everything he wears a plain black longsleeve turtleneck shirt, over that he wears a sleeveless white button up collared shirt, the bottom half consists of black shorts with a slight flare, connecting the two parts is a black waist cincher style corset. Over that he wears a harness sort of thing made from a faded black denim like material; the top portion is a standard, oversized drawstring hood (which he usually keeps on in a way that leaves his bangs uncovered) connected to the rest of the piece via vertical heavy-duty straps run down the front and back in a curved, ergonomic hip panel. This section wraps around the sides of the torso, leaving the chest and back open, in each hip sits a main mid size utility pouch with multiple smaller compartments inside (where his scrolls and smaller items like kunai are kept), outside of the main compartment. Then there are the flared black leg warmers/ boot covers pooling at his ankles and reaching up just above his knees, they're held up with red buckled thigh straps that clip onto the hem of the cincher and strap around his thighs, with the end clipped to the upper 'cuff'of the warmers. For shoes Tenma wears hiking boots with slightly higher wedge platforms. Over everything he wears a midriff Akatsuki styled jacket; he used remains of Itachi's cloak (post Sasuke battle so it was not in the best condition) to line the outside, keeping the high collar and long sleeves, while the inside is the same red but he made it thicker, water proof, and warmer. It is quite oversized so the sleeves extend down to his knees beyond his hands (so he adjusted the sleeves into more front open sleeves design to not sacrifice mobility) and he usually wears it off shoulder, so part of his right shoulder is exposed. And also by 13 he started looking a lot like Itachi, down to the tear-troughs.

Part I
- Description
He was a small child, with jet-black hair in a tiny ponytail and framing bangs. He wore a simple dark blue high-collar shirt, black trousers, a miniature raincoat, and sturdy waterproof boots. His frame is notably small.
Part II
- Description
He retained the high-collar style but shifts toward functional shinobi gear. By the time he awakens his Mangekyo, his hair is more unruly and his features sharpen. He mostly kept the same style as before.
Boruto
- Description
His most radical shift. Now a Kara member, his hair is shorter with a long right fringe covering half his face to mimic Deidara, featuring a dark blue dyed undertone. He wears subtle eyeliner, teal nail polish, and a "Techwear" ensemble: a black turtleneck, white sleeveless button-up, flared black shorts with a waist corset, and a denim utility harness with an oversized hood. He finishes the look with black leg warmers with red buckles/straps, wedge hiking boots, and a midriff-cut jacket repurposed from the remains of Itachi’s cloak, with a Roman numeral "X" tattoo on his right cheek.
