That guy is said to have the biggest sword, they write where it's located atm, and even his own biography is close to Gutts as they say:
"Approximately 7 kilometres (4.3 mi) to the north-east of Donia's village of Kimswerd, in the city of Franeker[9], the Black Band, a Landsknecht regiment in the service of George, Duke of Saxony was quartered. The regiment was charged with suppressing the civil war between the Vetkopers, who opposed Burgundian and subsequently Habsburg rule, and the Schieringers.
The Black Band were notorious as a violent military force; when their pay was insufficient or lacking, they would extract payments from local villagers[10] and on 29 January 1515, the Black Band plundered Donia's village, then allegedly raped and killed his wife, Rintze Syrtsema, and burnt to the ground both the village church and Donia's estate.[11][12] Seeking revenge, Pier started a guerrilla war campaign against the Habsburgs and allied himself with Charles of Egmond, Duke of Guelders (1492–1538), the foremost opponent of the Habsburgs\\'"
His image is also reminding Gutts - the way he holds his sword
