The 1984 Basic Set generates a new hero in six steps:
| Roll | Origin | What it means |
|---|---|---|
| 01–30 | Mutant | Powers from genetic changes (X-Men, Magneto). |
| 31–55 | Altered Human | Powers from an accident, experiment, or radiation (Spider-Man, Hulk, Cap). |
| 56–70 | High-Tech Hero | Powers from technology or gear (Iron Man, Punisher). |
| 71–80 | Robot | Mechanical being (Vision, Machine Man). |
| 81–95 | Alien | Born on another world (Thor, Silver Surfer). |
| 96–00 | Mystical/Other | Magical origin or other (Doctor Strange). |
The origin doesn't determine specific powers — it sets up the in-fiction explanation for why the character has powers, and may modify how many powers they roll (mutants and aliens tend to get more; high-tech heroes get devices instead).
For each of the seven abilities (Fighting, Agility, Strength, Endurance, Reason, Intuition, Psyche), roll d% and consult the Random Ranks table:
| Roll | Rank | Number |
|---|---|---|
| 01–05 | Feeble | 2 |
| 06–15 | Poor | 4 |
| 16–35 | Typical | 6 |
| 36–60 | Good | 10 |
| 61–80 | Excellent | 20 |
| 81–90 | Remarkable | 30 |
| 91–95 | Incredible | 40 |
| 96–98 | Amazing | 50 |
| 99 | Monstrous | 75 |
| 00 | Unearthly | 100 |
Origin-specific modifiers may apply — robots typically get higher Endurance, mutants get a free shift up on one ability, etc. Check the origin write-up in the Campaign Book.
Number of powers depends on origin (mutants and aliens tend to get more; high-tech heroes get devices instead of innate powers). Typical: 1–4 powers.
For each power, roll on Table 27 to determine the category, then on the sub-table to determine the specific power. Some powers (marked with an asterisk) are "special" and count as two regular powers.
Each power has a rank, rolled the same way as abilities.
Full list: Powers.
Roll for 1–3 talents, depending on the hero's origin and background. Roll d% on Table 30 (Talents) for each. Starred talents are special and count as two regular talents.
Full list: Talents.
