This time I tried with 2 characters and that one had 2 forms, the truth was a little difficult at first, since one stood out more than the other, but in the end I solved it.

• Gene Belcher: base + electric love

• Alex Papasian: base

The dual images are made with couple reforge, so I don't think they are replicable in civitai.

step: 20+/30+ | strength: 0.9-1 | cfg scale: 5-4 | clip skip: 2 | DPM++ 2M/Euler A

For correct anatomy according to the series, use:

1. (bb-alex), (aged down), chubby, glasses, 1boy, male focus, solo,

   • white t-shirt, red raglan_sleeves, short sleeves, blue pants, black sneakers,

   • grey t-shirt, short sleeves, blue pants, roller skates,

   • gym_uniform, grey t-shirt, aqua shorts, black sneakers,

   • green t-shirt,

2. (bb-gene), (aged down), plump, 1boy, solo,

   • yellow t-shirt, blue shorts, white socks, red sneakers,

   • white v-neck_shirt, light-blue raglan_sleeves, short sleeves, light-blue shorts, brown slippers,

   • topless, green swim trunks, barefoot,

   • topless, white underwear, barefoot,

   • white alternate hairstyle, thick eyebrows,

     • black suit, black coat, white shirt, black traditional bowtie, black belt, black pants, black footwear,

Optional sleeping Gene: sleeping, top-down_bottom-up,

Optional change: chubby -> plump | aged down -> young

It's better for Alex: male focus,

Negative prompt: double chin, alternate_color, ((expressionless)), old, old man, aged up, pectorals, bara, muscular, muscle, obliques, ((nostrils)), normal nose, multicolored theme, obese, chibi, bad anatomy,

Testing: WAI-NSFW-illustrious-SDXL v11

• blurry, low quality, bar censor, censored, mosaic censoring, bad quality, worst quality, worst detail, normal quality, sketch, censor, simple background, double chin, alternate_color,

• few detailed, bad detailed, worst_detailed, sketch, simple background, blurry, censor, bar censor, censored, mosaic censoring, ((nostrils)), pectorals, bara, muscular, muscle, obliques, ((expressionless)), wavy mouth, double chin, clone, clone harem, multicolored theme, normal_nose, mutation, mutilation, ((solo, solo focus)), detached limbs, makeup, obese, chibi, bad_anatomy, (3digits, 3 digits, extra digits, 3fingers), extra digits, odd fingers, extra_fingers, sweatdrop, static_expressions, 3boys, 3person, ((size difference, age difference)), head out of frame, chest_focus, two-tone hair, covered face, convenient censoring, hidden_face, bad angle, bad_mouth, bad_expression, ponytail, father and son, father, realistic, gradient hair, only focus, buck teeth, pov, person out of frame, tall body, short body, glasses, shota, child, aged down, pointing nose, (constricted pupils:0.5), toddler,

Notes:

• Most of the tests I did in "DPM++ 2M", I don't know how good it will be in "EULEAR A"

  • A combination is best for DPM/Euler A

• Scenario before the break

• If you are going to make the 2 characters at the same time it is better not to use the alternative version of Gene or to use it in an adetailer

• The number of two may vary between 4 and 5

• With flat color is more accurate to the series

• The last negative prompt is used for both characters

• If using "dot eyes", use "(constricted_pupils:0.5) at negative prompt

• Alex

  • Use male focus to avoid feminine features

• BREAK

  • If you are going to use it, it is better to put all the tags separated from the LoRA with a BREAK (for more details check the info in the images).

Example Couple Reforge:

high quality, masterpiece, amazing quality, colorful, best quality, detailed background, "INSERT_SCENARIO", ((duo, 2boys)), friends, BREAK, <lora:alex+gene-v4-07:0.9> (aged down), "[angle..., from...] <- optional"

((bb-alex), brown hair, chubby), 2boys, male focus, glasses, "individual clothing, individual action"

((bb-gene), black hair, plump), 2boys, no eyeweard, "individual clothing, individual action"

Notes:

• For some reason I get better results by indicating “no eyeweard”

• The example given is for general first line

• Is better with a mask

• No need to wear glasses or male focus

• Could be better to add "aged_down, young"

• I recommend to look at the information of the images with both characters.
