This LoRA faithfully recreates Isaac Martinez, the highly versatile original character (OC) from AU 777 and multiple fan-made alternate universes of The Loud House. Isaac is the son of Consuelo Martínez. His occupation and alignment change drastically depending on the AU: he can be a time traveler, dimensional traveler, student, hero, villain, guardian, or even an artificial intelligence.

The model locks in his most common canonical fan appearance: a young Latino (Mexican) male with tan skin, short to medium brown hair, sharp features, and a noticeable scar on his face (usually on the cheek or near the eye). He almost always wears clothing in black and blue tones — commonly a black jacket or hoodie with blue accents, dark pants, and sneakers.
